Tom Rothman micromanaging has nothing to do with the continuity issues in First Class, though. Crippling Xavier at the end was Vaughn's decision, having Magneto and Xavier meet as men in their 30s - Vaughn, having Beast look more feline - Vaughn. Those are such minute things, that I can't see Fox execs wringing their hands and cackling in the dark about how they are going to screw the X-Men fans with the continuity issues.

This is the case where you can't blame the studio.

Fox did have the Beast make-up altered once or twice during filming, so the Rothman gang was doing some micromanaging....
